The attribute WGALLOWEDIP_A_IPADDR can contain either an IPv4 or an IPv6 address depending on WGALLOWEDIP_A_FAMILY, however in practice it is enough to look at the attribute length. This patch implements an ipv4-or-v6 display hint, that can deal with this kind of attribute. It only implements this display hint for genetlink-legacy, it can be added to other protocol variants if needed, but we don't want to encourage it's use.
